In Pictures: Least Fuel-Efficient Hybrids

2007 Chevrolet Silverado Classic 15 Hybrid 4WD

Gas mileage: 16 miles per gallon

Estimated fuel cost per year: $2,625

MSRP: $29,310

You could drop $85 filling up the tank on this gas-guzzling hybrid truck. The V8, 5.3-liter engine only gets 16 miles per gallon, but is far more efficient than the conventionally powered model, which gets 10 miles to the gallon.
